engineering chain division maintenance checkpoints checkpoints centering comments a guide rail is essential to ensure proper centering of the conveyor if centering is not accurate with no side guide rail scrubbing of the sidebars will occur which results in shorter conveyor chain life and/or possible chain failure when two or more sprockets are installed in a row be sure to align the position of the sprocket teeth if the sprocket teeth are not properly aligned the working load will not be equally divided and will cause the chain to twist to align sprockets quickly easily and effectively contact u.s tsubaki for information about the pro-aligntm laser alignment system if take-ups on both sides are uneven the conveyor chain will not engage smoothly with the sprocket maintain adequate chain slack if chain tension is too high loss of power will result this is a dangerous situation and if too loose the chain will climb the sprocket the first running of the system after installation should b
